Forewing with 2nd cubital cell two-and-a-half times as long, measured along the cubitus, as high, measured vertically from the cubitus to the junction of the 1st and 2nd abscissae of radius.

Doryctes ambeodonti Muesebeck, 1941. (Figs. F and G.)

1941. Doryctes ambeodonti Muesebeck. Proc. Entom. Soc, Washington, Vol 43. No 7, p. 149.

Muesebeck described this species from 24 females and 2 males collected at Papakura, Auckland and reared by K. Harrow, from Ambeodantus tristis (Fabr).

This species has been adequately described by Muesebeck, but the following combination of characters will serve to distinguish it from other known Now Zealand species.

Malar space about two-thirds of the vertical diameter of the eye; ocellocular space is slightly over 1½ times the length of the space between the posterior ocelli and the occiput carina; ocellar triangle with the base longer than the length of the sides; scape shorter and relatively thicker, being only a little longer than its greatest diameter; flagellum with 1st segment about 1½ times as long as 2nd segment; usually the pronotum is considerably darker than the surrounding sclerites, in some specimens nearly black; the absence of the median longitudinal fovea on the frons and face, although it is present between the bases of the antennae; wings uniformly infumated; abdomen with 1st tergite about as broad apically as long, and with basal three-quarters laterally carinate, a short carina running obliquely inwards from each of the anterior lateral corners, the whole tergite medially convex; 1st abscissa of, radius is subequal to the greatest width of stigma; 2nd cubital cell is three times as long as its greatest height. Wings as figured. (fig. F.)

The above notes were made from several paratypes in the collection of the Plant Diseases Division, Auckland.

Distribution. Auckland Province, New Zealand.

Colour. Head dark brown to black, antennae concolourous with head; thorax and propodeum black to black-brown; tegulae and legs brown; abdomen with 1st tergite black-brown, remaining tergites dark-brown; ovipositor, stigma and veins dark-brown; a light spot at base and apex of stigma; lower portion of 1st transverse cubitus, and the 2nd transverse cubitus veins unpigmented.
